Oooh, +1 to the Sonata Proto: very nice cases. The older version used to have a fantastic air guide that ducted air from floor level at the back (where it should theoretically be cooler) pushing it into the case above the CPU and where a graphics card would typically sit. In fact, a lot of Antec's cases seem to have been slowly downgraded over the last 5 - 10 years. Still good cases, but not as good value as they used to be...
